There has been some discussion on doing this conversion and I just wanted to add my 2 cents on it.
The part # is 20874 and can be had at most of your local parts stores. It comes off a 1988+ Chevy S10 Pickup (4cyl). This is a direct bolt up and the holes line right up. The major difference is a nipple which is L shape on the rover pump is a straight shape on the GM pump, this nipple connects to a hose that goes to the reservoir. To make it work you must buy 3 ft of hose and loop it over the top of the pump just beneath the radiator hose. This will make it so it does not kink.
Other tools you?ll need is a pulley puller to remove the pulley attach to rover pump and place it on the GM pump.
I am not doing a full write up of this (may already be one). My impression has been that it provides much more power for turning, it?s a big difference. The pump does whine slightly. Your avg DD would probably be better off with the regular rover pump (cuz it whines a little and you?ll probably bitch), but any serious offroader would greatly benefit doing this conversion.
Purpose of upgrade:
To gain higher flow pump to increase steering capability
Required Tools:
basic hand tools
pulley puller (rentalable at parts store)
Tips:
Do this while the engine is cool. Buy 3 feet of hose for the hose going to the reservoir. Pretty straight forward swap. Take out old unit and replace with new.
